The Algebra LearnLab course is described here.
The Algebra LearnLab course involves teaching high school Algebra I using the textbook and tutoring system of Carnegie Learning. The curriculum combines software-based, individualized computer lessons with collaborative, real-world problem-solving activities. Students spend about 40% of their class time using the software, and the balance of their time engaged in classroom problem-solving activities. Three Pittsburgh-area high schools are currently participating as PSLC Algebra LearnLab sites, offering a diverse student population, and additional high schools around the country are anticipated for future participation. Algebra I topics include:
- Organizing Single Variable Data
- Simplifying Linear Expressions
- Finding Linear Equations from Graphs
- Solving Linear Equations and Inequalities
- Standard Form
- Slope Intercept Form
- Mathematical Modeling
- Linear Expressions and Equations
- Quadratic Expressions and Equations
- Solving Systems of Linear Equations Algebraically and Graphically
- Solving and Graphing Equations Involving Absolute Values
- Problem Solving using Proportional Reasoning
- Analyzing Data and Making Predictions
- Powers and Exponents
Numerous studies in the algebra LearnLab course can be found in all three of the research clusters: Coordinative Learning, Interactive Communication, and Refinement and Fluency.
